LOOSE-LEAF BINDER AND HOLDER.

Specification of Letters Patent.

Patented July 17, 1917.

Application filed October 25, 1915. Serial No. 57,682.

To all whom it may concern:

Be it known that I, BEN AMIN F. DAVIS,

a citizen of the United States, residing at the city and county of San Francisco and State of California, have invented new and useful Improvements in Loose-Leaf Binders and Holders, of which the following is a specification.

This invention relates to a loose leaf binder and holder.

The object of the present invention is to provide a simple, substantial, cheaply manufactured loose leaf binder and holder, particularly constructed to receive sheet music; papers; various forms of periodicals and other matter, and which is so constructed that the sheets or leaves may be quickly and easily inserted or removed at any point without disturbing 0r disarranging the remaining sheets, and in which the sheets will always remain perfectly fiat when opened and in a position where the individual sheets or leaves in the binder may be easily grasped and turned. Further objects will hereinafter appear.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings in which Figure 1 is a perspective view of the binder and holder, showing the leaves secured therein in an opened position.

Fig. 2 is a perspective view of the binder proper. 4

Fig. 3 is a perspective view of one end and the rear side of the binder, showing the .means by which the sliding plate is secured.

Fig. 4 is a view similar to Fig. 1, showing the leaves turned to one side.

Fig. 5 is a central, longitudinal section on line 5-5, Fig. 4.

Fig. 6 is a perspective view showing one form of the holder, in which the binder is inserted.

Referring to the drawings in detail, Aindicates in general the binder proper, which consists of amain plate 2, on one end of which'is secured by hinges 3,-an extension plate 4 whichis normally held in a locked position or in alinement with the main plate by means of an overlapping or book shaped projection 5, formed on the plate 6, which is slidably mounted on the rear side of the main plate and held in position by a bracket plate 7, which is secured to the main plate by lugs 8 and screws 9. The bracket plate 7 is slotted as at 10, and apin 11 projecting through said slot and secured to the sliding plate, limits the movement of same or prevents the sliding plate from being com-v pletely removed or disengaged with relation to the main plate 2 and the bracket plate 7 The binders securing the leaves B in position are here shown as consisting of a plu- The binder proper comprising the main plate 2; the pivotally mounted extension plate 4; the sliding plate 6 and the strings 15 and 16 is adapted to be inserted and secured in a channel shaped holder, such as indicated at 17, in Figs. 1, 4 and 6. The channel shaped holder is made in two forms; one form being shown in Figs. 1 and 4, is provided with leaf extensions 18 and 19, which are secured to the channel shaped holder 17, as at 20, in a manner similar to the covers on a book; thus giving the holder with inserted binder A, the appearance of a book. The other form of holder is shown in Fig. 6; this is used for filing purposes and the cover extensions 18 and 19 are therefore, not necessary.

For the purpose of securing the binder A in the channel shaped holder, that is against removal in the direction of arrow a, see Fig. 6, a tongue projection 22 has been provided on the bracket plate 7, which engages with a pocket 28 formed in the bottom of the channel shaped holder, when the binder proper is inserted into same by sliding it in endwise through the open end, indicated at 24. The binder is further secured against removal in the direction of arrow at by a cross strip 25 the bracket 23 through which it extends.

when the binder is inserted.

- In operation with the binder inserted in the hook shaped holder, indicated in Figs. 1 and 4, when it is desired to insert a copy of sheet music or other forms of sheets, it is only necessary to pull the sliding plate Ollt.

' lifted about the hinge 3, until it assumes approximately the position indicated by dotted line 27. This movement of the extension plate about its hinge 8 slackens the strings '15 and 16 and permits the individual sheet to be inserted in such a manner that one string will extend across the center of two connected pages, as shown in Fig. 1, or in a position where it will engage a fold 28, formed on the inner end of a sheet, particularly where a single sheet is inserted. After the double or single sheet or a collective number of sheets have been inserted beneath one or more strings, the extension plate is depressed until it assumes the position in Y *alinement with the main plate; this movement of the extension plate pulls the string back into taut position, thereby securing the leaves from removal and is secured in this position by moving the sliding plate back until the hook 5 engages or overlaps the plate 4. v r

The offset spacing of the short and long strings 15 and ltl'permits the selection of an individual or desired sheet more readily,

than if the strings were all of equal length; this being the main reason for the spacing and alternation in the length of the strings.

From the foregoing description, it will be seenthat the insertlon or removal of an individual or collective number of sheets is 'quickly and easily accomplished, as it is only necessary to'move the sliding plate to release thehinge extension plate, so that the tension of the strings may-be sufficiently relieved to slacken same.

Any sheet can therefore, be removed or inserted at the will of the operator without disarranging or releasing any of the other sheets. ,After the binder has been completely-filled. it may be removed from thebook-like holder, indicated at 1 and 4, by inserting the finger through an opening 30, formed in the end of the holder and applying sufiicient pressure to move the binder endwise in. the holder in the direction of arrow 0 until it becomes disengaged with the cross piece 25 and the bracket 28; it is then lifted out and preferably inserted in the form of holder shown in Fig. 6, which is similar to the holder indicated in Figs. 1 and 4'.

' With the exception that the cover sections filing purposes, and the rear side or back of same may act as a receiver upon which a list or index showing the contents of the binder may be placed or otherwise secured. Sheet music, periodicals, papers or other matter may in this manner he quickly and easily filed and indexed. Another important feature of the present invention is the mounting of the leaf securing means, comprising the strings l5 and 16. The parallel position and interspacing of same permits the leaves when opened to assume a perfectly fiat position, as they have no tendency to close upon themselves, as is common in ordinary books or most forms of filing binders now in use.

Another advantage secured by the present construction of the binder, is the case and manner with which a single sheet may be inserted; this being accomplished by merely folding the inner edge of the sheet, as indicated at 28, see Fig. 1, and inserting this under the desired string to assume the position shown. The string when pulled taut by the hinged extension plate positively secures the sheet from removal and at the same time permits it to assume a flat position; this manner of securing and holding a single sheet leaf, is furthermore an advantage, as the outer edge 35 of the sheet is sufficiently pulled in to separate it from the remaining sheets, thus permitting it to be more easily grasped or secured, when it is desired to thumb or turn the leaves.

The binder and holder constructed as here shown, is simple, substantial in construction, cheap to manufacture and quickly and easily manipulated when the sheets are to be inserted or removed.

The materials and finish of the several parts of the device may be such as the judg- I wish it understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims, and that I do not wish to limit myself to the specific design and construction here shown.

Having thus described my invention, what I claim and desire to secure by Letters Patent is- 1, A loose leaf binder comprising a main plate having a rigid and a movable section, a plurality of strings on one side of the plate disposed parallel with each other, and secured at one end to the rigid end of the plate and at the other end to the movable section, and a holder into which the main plate is adapted to fit, and interengaging means on said plate and holder for securing said plate to the holder.

2. A loose leaf binder comprising a main plate, a hinged section on one end of the plate, a plurality of strings on one side of the plate disposed parallel with each other and secured at one end to the plate and at the other end to the hinged section, and a slidably mounted latch having a hookshaped projection movable into and out of engagement With the swinging end of the hinged plate.

3. A loose leaf binder comprising a main plate, a hinged section on one end of the plate, a plurality of strings on one side of the plate disposed parallel With each other and secured at one end to the plate and at the other end to the hinged section, a plate slidably mounted on the other side of the main plate, and a hook shaped extension on the sliding plate adapted to engage the hinged member to lock it against movement on the hinge.

4. A loose leaf binder comprising a main plate, a hinged section on one end of the plate, a plurality of strings on one side of the plate disposed parallel With each other and secured at one end to the plate and at the other end to the hinged section, and a holder into Which the main plate and hinged section are adapted to be inserted and secured.

5. A loose leaf binder comprising a main plate, a hinged section on one end of the plate, a plurality of strings on one side of the plate disposed parallel With each other and secured at one end to the plate and at the other end to the hinged section, a plate slidably mounted on the other side of the main plate, a hook shaped extension on the sliding plate adapted to engage the hinged member to lock it against movement on the hinge, a channel shaped holder into Which the main plate, sliding plate and hinged member are adapted to be inserted, and a hook shaped projection on the main plate engageable With a pocket in the holder to secure the main plate against'removal.

6. A loose leaf binder comprising a main plate, a hinged section on one end of the plate, a plurality of strings on one side of the plate disposed parallel With. each other and secured at one end to the plate and at the other end to the hinged section, a plate slidably mounted on the other side of the main plate, a hook shaped extension on the sliding plate adapted to engage the hinged member to lock it against movement on the hinge, and means for limiting the movement of the sliding plate.

7 In a loose leaf hinder, the combination of a backing member With a tension cord over Which the sheet is folded, means for tightening and loosening the tension cord, and a channel shaped holder adapted to receive and support the backing member.
